CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 35 8,337, dated January 18, 1887.

Application filed July 2, 1886; Serial No. 206,929.

.light liquid hydrocarbon, whereby the air is carbureted and becomes an illuminating-gas or gaseous vapor. g The object of my invention is, in general, to

improve and simplify the construction of the carbureting-ehamber, which is sectional, the several sections being mounted upon each other, and the same pipe is utilized for supplying the chamber with the liquid hydrocar-' bon and for admitting the air to be carbureted. Thus I am enabled by superimposing the several chambers of the carbureter to fill all with the liquid up to the overflow-outlet by the same pipes and passages used for the air.

The construction of my invention will be hereinafter fully described, and its novel features carefully defined in the claim.

In the drawings,which serve to illustrate my invention, Figure l is a side elevation of a carbureting apparatus embodying my invention, wherein the upper carburet-ing chamber is shown partly in section, so as to disclose the interior arrangement. Fig. 2 is an end elevation, partly in section, of the lower carbureting-chamber. In this figure the chamber is drawn to a larger scale than Fig. 1, in order to better disclose the interior construction. Fig. 3 is an enlarged sectional view of the Fig. 4 is a sectional view of a blower or air-forcing apparatus such as I prefer to and usually do employ in connection with my carburetor, the plane of the section being taken substantially on line 4 4 in Figs5. Fig. 5 is a transverse section of the said air-forcing apparatus, taken in the plane indicated by line 5 5 in Fig. 4.

In the drawings I have shown lily-apparatus as supplied-with air under pressure by a blower-pump or air-forcing apparatus, A, of

a well-known construction, run by a weight or spring. Such devices are not new, and, indeed, it is immaterial from what source the air under a moderate pressure is derived, so far as my present invention is concerned. I will, however, briefly describe the apparatus or device I prefer to employ, as illustrated in Figs. 4 and 5.

WVithin the exterior casing, A, which is cylindrical, is mounted rotatively a shaft, 0, which carries four chambered buckets, D D, set somewhat spirally or obliquely with respect to the shaft, their forward ends (when the sh aft is being rotated) standing at the right hand in Fig. '4. The casing A is filled with water or other liquid up to the level indicated by dotted line m x, and as the buckets revolve the end margins or lips of the buckets at the right-hand end first dip into the liquid, and as the bucket is gradually submerged the air is crowded to the left-hand end, where it escapes into the casing from that end of the buckets, the spiral or oblique mounting of the buckets causing the end opening in the buckets at the discharging or left-hand end to rise above the water-level by thetime the receiving end is submerged. The airin casing A, which is under moderate tension, is led to the carbureting-ehamber, as will be hereinafter described.

On the receiving or right-hand end of the four connected buckets is secured a concave plate, 1), which forms an air-receiving chamber open to all the buckets. Air from without is admitted to this chamber by a bent tube, 9, which passes under the liquid and through a central opening, 0', in the plate '1), around shaft 0, and wholly below the water-level, so as to be sealed.

On shaft 0 is fixed a ratchet wheel, 8, and on a shaft, t, mounted in a bracket, to, is a pawl, s, which engages ratchet s. Shafts 0 and tare aligned, but independent. On shaft t is fixed a Windlass barrel or spool, 2), on which is wound a cord or chain, w, to which is attached a weight, 3 This weight, operating through the cord 10 and pawl and ratchet, rotates the buckets, as described. The weight is wound up the same as a clock-weight. v

I will now proceed with the description of the carburetor proper.

ICO

B is the carburetor proper or carbureting vessel, which is composed of one or more carbureting vessels or chambers, numbered 1, 2, and 3 in Fig. 1. These chambers are all alike, or may be all alike, and they are capable of being mounted one on top of another and coupled together, as shown, so as to increase the carbureting capacity of the apparatus to any desired extent. Each chamber is made, by preference, ofrectangular or box-like form and of galvanized iron flanged and riveted together. The interior of the chamber is provided with numerous strands, a, of some fibrous material, which may be of candlewieking or of other loosely-twisted cheap fiber. These strands are arranged vertically in the chamber and close together, so as to nearly touch each other. A convenient plan of mounting the strands is illustrated in the drawings, and this consists in arranging a series of rods, 1) b, Fig. 2, on supports near the roof or top of the chamber and suspending the strands a from these; and to keep them in place on the rods 1), I usually pass the strands around similar rods, 1), arranged at the lower part of the chamber. This may be conveniently effected by winding the strand continuously back and forth from a rod, 1), to the rod 1), below it.

From the blower A a pipe, 0, leads the air to the upper chamber, 1, where it enters near the roof or top plate, as seen in Fig. 1. In order that the incoming current of air may be broken up and scattered or diffused, I prefer to house the inlet with a sheet-metal box, D, which may extend the entire width of the chamber, and to perforate this box for the escape of the air therefrom into the carburetingchamber. At the opposite end of chamber 1, and on about the same level as the inlet, is

the outlet 0, and a pipe, f, connects this outlet with the inlet to chamber 2. This chamber is constructed precisely like chamber 1, and its outlet is connected by a pipe, f with chamher 3, which is also constructed like chambers 1 and 2. From chamber 3 the carbureted air is led bya pipe, 9, to the mixer O, (hereinafter described,) and passes thence to the burners by a plpe, g.

The naphtha, gasoline, or other light liquid hydrocarbon is supplied to-the carbureting chamber 1 by or through air-pipe c, the filling inlet It being provided with means for hermetically closing it when the filling has been effected. The filling operation is as follows: The liquid hydrocarbon is poured in at the inlet h and nearly fills chamber 1. It then overflows at outlet e, and nearly fills chamber 2. From thence it overflows into chamber 3, and is permitted to rise therein nearly to the outlet into pipe 9. Thefilling-inlet his now tightly closed and the capillary absorbing quality of the wickingstrands a will cause them to take up the liquid in the chambers and hold it as a wick holds oil.

By arranging the inlet and outlet for the liquid hydrocarbon near the roof or top plate of the chamber, I gain two important advantages, The roof-plate is so low that the air in flowing across to the outlet is kept from rising above the vapors, as it will do in carburetors where other constructions are used. I am also enabled to retain a greater quantity of the hydrocarbon by reason of the overflowoutlet being so near the roof or top plate. By utilizing the air-pipe and inlet for the hydrocarbon-inlet also I not only cheapen the carburetor, but I greatly simplify its construction and avoid joints, which are sure to result in leakage and danger. My peculiar arrangement of the outlets and inlets and the superimposition of the carbureting-chambers enables me to thus simplify the construction.

In order that the attendant may be able to judge when the lower chamber, 3, is filled to the proper level, I provide said chamber with an ordinary glass-tube gage, v3, or some other lings, so that a chamber or section may be conveniently added or removed. For example, suppose that each chamber or section is capable of carbureting air enough to supply five burners. I have then a unit or standard section. For any number of burners from five to ten, two sections would be coupled together. Forany numberof burners from five to fifteen, three sections would be coupled together. Four sections would suffice for twenty lights, and so on.

Thus I am enabled to construct carburetors having a wide range of capacity from only one style and size of chamber, and so avoid the expense attendant upon the manufacture of a numberof sizes and styles. The capacity of the air'forcing apparatus A may be increased by increasing its size, and the pressure or tension may be regulated by increasing or diminishing the size of the weight 3 I will now describe the operation of diluting the carbureted air with ordinary air to prevent smoking at the burners and the devices employedto effect this result.

It is well known that to produce a white light and to prevent smoking at the burners the proportions of hydrocarbon vapor must bear a certain relation to the air with which it is mixed. If the carbon is in excess, the

combustion will be defective and the flame If oxygen in sufiicient quantity is vided with a cock, m, by preference, although j are constructed with readily-detachable coup- I do not deem this cock essential. An airpipe, n, from blower A, connects with the airinlet k, and the carbureted-air pipe 9 taps the hollow shell or bodyj at some point back of the tip of nozzle Z. By manipulating cock is the exact quantity of air required from the blower may be admitted to the mixer,and the pressure thereof may be regulated.

It will be seen that in this device the air from the blower and the carburetedair from chamber 3 reach the diluter 0 under nearly the same tension, the air from the blower having normally, however, a somewhat greater tension than the carbureted air, for the reason that it is direct. This jet from the blower acts as an injecting-jet, and the mixed gases pass to the burners through pipe 9.

Any back pressure from the burners will be transmitted from the blower equally through pipes g and 7t, and it will not be possible for this back pressure to drive the carbureted air out into the atmosphere at the air-inlet, as in carburetors where the air is taken by injection from the atmosphere. Nor will the aircurrent direct from the blower tend to force the carbureted air back toward the carburetor, owing to its normally greater tension, as in some styles of carburetors.

I wish it understood that I am aware that it is not new to pack chambers of carburetors with absorbent materials arranged in vertical strands like wicks saturated with volatile hydrocarbons, and to pass or force air through such chambers in succession, and this I do not claim.

In lieu of strands a, arranged vertically in the chambers of the carburetors, I may employ sheets of fabric arranged to stand vertically therein and close together. be passed over the rods 12 b,and would present the appearance of the strands a in Fig. 2. I might also employ one blower or air-forcing apparatus to supply air to the carburetingvessel 13, and another to supply air direct to the mixer O. I prefer to use one apparatus for both, however.

When charging the carburetor with liquid hydrocarbon, the air expelled may be allowed to escape at a cock, g, in pipe 9.

Having thus described my invention, I claim A' carburetor comprising two or more superimposed box-like vessels, 1 2, each provided with frames having on them a fibrous absorbent material, and with an air-inlet and an air-outlet at opposite ends of the vessel, said inlets and outlets being arranged close to the top plate of the vessel, and the outlet of one vessel being connected with the inlet of that next below,a pipe, 0, for air,and a fillinginlet, h, for liquid hydrocarbon, connected with the air-inlet of the upper vessel,1, a pipe from the outlet of the lower vessel to the burners, a second pipe connecting the lower with the outlet pipe,and the injector and regulator connecting the two pipes, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
